As shown in fig. 3, when a left-side flow comes, a part of the water flow at the inlet of the first turbine rotor 2 is guided to the propulsion blades on the first turbine rotor 2 through the first S-shaped guide plate 401, and a part of the water flow at the inlet of the first turbine rotor 2 is blocked by the first arc guide plate 501, so that the resistance of the water flow to the rotating blades on the first turbine rotor 2 is reduced, and the water flow is divided to the propulsion blades on the second turbine rotor 3, and the guide plate simultaneously plays a forward role for the two turbine rotors, thereby greatly improving the power generation efficiency; when the water flow direction changes, the water flow action principle is the same. Therefore, the invention can realize bidirectional synchronous driving without changing the direction of the guide plate manually.
As shown in fig. 1 and 4, the S-shaped guide plate 4 is formed by tangentially arranging two arc surfaces at the end parts of two arc plates with the same curvature, wherein one arc plate is coaxial with the turbine rotor close to the S-shaped guide plate 4.

As shown in fig. 4, the two arc guide plates 5 installed in the middle of the guide box body 1, when a left-side incoming flow, the first arc guide plate 501 can reduce the impact on the rotating blades of the first turbine rotor 2, and simultaneously, the first arc guide plate plays a role in guiding the flow of the propelling blades of the second turbine rotor 3, and the second guide plate 502 has the same function; the two circular arc guide plates 5 leave enough circulation space between the two rotors to enable the two turbine rotors to generate coupling action. Therefore, the dual-purpose characteristic of the two guide plates 5 arranged in the middle of the guide box body 1 and the coupling gain effect when the Sambus rotors are arranged are the main reasons that the power generation device can realize the parallel installation of the multiple rotors.
